Our invention relates to improvements in filling mechan sms, especially the filling mechanisms which fill bottles with carbo- .nated water under low a1r pressure, and it the act of drawing the carbonated water through a wire mesh. It is'a well known fact that in wiredrawing carbonated water, the

velocity of the water is increased and a portion ofthe gas escapes therefrom.

A further object of ourv invention is toprovide a device of the type described with which a lower carbonator pressure is used to pass the same a mount of gas into a beverage that is obtained with the old system.

' A further object of our invention is to provide a device of the type described with which irrespective of any possible air leaks there- A further object of our invention is toprovide adevice of the typedescribed which obviates the necessity of refrigeration of the water in orderto pass the desired volume of gasinto the beverage. l

' Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

Out invention is illustrated inthe accompanying drawings, forming part of this application in which Figure 1 is a diagrammatic view. ofthe de vice,

Figure 2 is ancnlarged sectional view of 3 the device, and

. 'Figure 3 isan enlarged sectional viewof a portlonoit' thedevlce.

i In carrying out ourrinvention, we provide I, .a carbonator 1 and a filling machine 2. The j fillingmachine is provided with a liquid tank 3. A pipe line 4 extends from the carbonator 1 to a point 5 within the filling machine 2.

A liquid control valve is positioned at the point 5 upon the pipe line 4. The liquid control valve consists of a housing 6 having an inlet opening 7, a compartment 8, and outlet openings 9 and 10. The inlet opening 7 is in communication with the pipe line 4:. A

pipe 11 is secured at one end to the housing 6 and communicates with the outlet 9. The free end of the pipe 11 is secured at 12 to the lower part of the tank 3 and communicates therewith. A pipe 13 is secured at one end to the housing 6 and communicates with the 1 opening 10. The free end of the pipe 13 is secured at 14 to the lower'portion of the tank 3 and is in communication with the tank. A valve seat 15 is disposed in the compartment 8, and is in communication with the pipe line 4. A valve head 16 having a valve stem 17 is adapted to engage with the valve seat 15. A diaphragm 18 is secured at its center to the valve stem 17 A compartment cover 19 is provided with packing 20 which not only prevents the liquid from escaping therefrom, but serves as a guide for the valve stem the water level in the filler tank is maintained 17. A diaphragm cover 21 and the peripheral edge of the diaphragm are secured to the compartment cover 19. r The diaphragm cover 21 is provided with an inlet opening 22 and an outlet opening 23. A valve 24 is secured to the diaphragm cover 21 1n communication with the outlet opening 23.

. A float valve is disposed in the tank 3 and consists of a tubular member 25 having a reduced end 26 which extends through the bottom of the tank3 and. is in communication with the inlet opening 22 by means of a tube 27. A head 28 is secured to the upper portion of the tubular member 25 and is pror vided with a vertically extending passage- 'way 29 and a horizontallyextendingpassage-- loo a certain amount of pressure.

A sleeve 31 is slidably disposed upon the tubular member 25 and is secured to the valve seat 3 by means of a stud 35 and an adjust able nut 36. Openings 37 are disposed in the side walls of the sleeve 34-. The lower end of the sleeve 34 is provided with an'outwardly extending integral flange38. A cam 39 which is actuated by a float 40 is pivotally mounted at 4:1 to .an adjustable bracket 42, and is in engagement with the flange 38. An air escape valve 43 is in communication with the liquid tank for permitting an undesired amount of air to pass therefrom.

From the foregoing description of the va-.

rious parts of the device, the operation there of may be readily understood. The carbonated water passes from the carbonator to the liquid control valve and into the tank under A portion of this'pressure is maintained in the tank 3,'the remaii'ider escaping through the valve 43. \Vhen the level of the liquid in the tank moves downwardly, the float a0 is lowered, thus actuating the cam 39 and raising the sleeve 34. 'By raising the sleeve 34, the valve seat 32 is also raised into engagement with the annular valve portion 31, thus closing the passageway 29. In this manner, the air pressure is shut ofl from the upper portion of the diaphragm i8 and the pressure of the carbonated water is sufficient to raise the valve 16 and the valve stem 17 upwardly, thus permitting the water to pass into the compartment 8 through the outlet openings 9 and 10 and into the tank. As the carbonated water flows into the tank,

the float 40 is raised upwardly, thus permitting the sleeve 34 to move downwardly and remove the valve seat 32 from the annular valve portion31. 'In this manner, air pressure is permitted to pass through the openings 37, the passageways 30 and 29, around the valve seat 32, through the openings 33, through the tubular portion 25, the tube 27, and into the portion between the diaphragm 1S and the diaphragm cover 21. The diaphragm 18 being greatly larger in diameter than the opening 7 permits a movement downwardly of the valve against the relatively high pressure of the carbonated water with a relativelysmall amount of air pressure. In this manner, the valve 16 is held closed preventing carbonated water from entering the tank 3 until the float 40 again moves d ownwardly.

By this construction, the level of the carbonated water within the tankis constanly maintained at a predetermined position. The level of the carbonated water within the tank may be changed byadjusting the float 40 and the bracket 42.

Theair above the diaphragm escapes slowly through the valve 24. The speed of the air passingirom above the diaphragm is govcrned by the valve 24.
